' PACKAGE 0F X-RAY FILMS. i

To all whom t may conce/m.'

- 'Be it known that I, JOHN G. J oNEs, citizen of the United States of America, 'residing at Rochester., in the county of Monroe and State of New York, have invented certain new and useful Improvements in Packages of X-Ray Films, of which the following is a full, clear, and exact specification.

`tion in part of my application, Serial No.

276,637, filed Feb. 12, 1919.

It relates more particularly to such a package in which is placed a sheet of foil of heavy metal 'such as tin or lead which is placed in back of the film and the edges of which are interfolded with the edges of a piece of protective wrapping paper, the intercrimped edges constituting a light-tight stifi'ening bead around the edge of the package. This tially opened to admit fluid but still be lighttight. The package particularly described is intended for use in dental work but the advantages of my inventionare not limited to such use. Other advantages will be evident from a perusal of the specification and inspection of the accompanymg drawings in Which:

age is shown in Figs. l to 9. This package consists of the following elements shown in Fig. 2: Two sheets of sensitized film 2 lying between sheets of protective paper l0 which may be water-proofed, an inclosing envelop of paper 4 having a continuous flanged edge 7 and a sheet of metallic foil 3 having a flanged edge5 and a sheet of'pper 11.

These elementsl are lhereshown in a convenient way so that their relative location may be readily and easily perceived. It is to be understood, however, that this figure is not intended to represent them as they are at any one time since the flange 7 may or may not be formed before any of the other elements are placed on'sheet 4l and flange 7 is necessarily bent before sheet 1'1 is added as will appear from the description hereinafter.

The sheets' of sensitized film 2 are placed between the sheets of protective paper l() and uponthese is placed the sheet 3 of metal foil with the upturned flanges 5. These assembled elements are placed on the sheet 4 in an unfolded condition. These various elements are assembled with -a die 14 fitting within the .flange 5 and directly above the die member paper 11 which may contain any desired printed matter. This sheet 11 is nowforced by any suitable die down within-the .flanges completing the bending of flange 8.. The sheet 11 fits snugly within the overturned flange. At this stage it is not pushedcom-D pletelyhome but'remains out of Contact with foil 3 as indicated in Fig. 6. In an other operation the combined flanges 5 and 7 are turned overvupon the sheet 11 which is i at the same time pushed down tightly into contact with the foil 5, as shown in` lEig. 7. The sheet of paper 11 has the function of insuring that the'fold 8 of the flange 7 can-v not become loose or unfolded afterthe paclrage is bent or submitted to rough usage. The bottom portion') of the flange 8 Will be securely caught around the edge of the paper 1l; the, flange 5 will be bent over into the overhanging flange 6 While the flange 7 will be bent over at 12. There is thus provided a bead 13 around the edge of the package Which is light-tight even under ad verse conditions of usage and moreover furnishes a strengthening bead which causes the package to hold its shape.

It is understood that While have described one method of manufacture the flange 7 may be formed about the .sheet .4C and the elements placed therein either singl -or as an assemblange or any other desire orvequivalent method of forming 'the packs age may be used.

An added advantage obtained by the structure herein disclosed is that the `package may be partially opened so as to lafford ready access to fluids for developing purposes. The operator may, therefore, after eiiposure 4of the film readily unfold the package With his fingers along one'edge and drop it into a tank of developer. To accomplish this purpose the piece ofpaper 11 is first crumpled or pinched by the fingers.A

and its edges thus drawn from under the overhanging flange 8 leaving the package in the condition shown in Fig. 8. The bead around part/of the package'is then straightened up with the finger nail and the tightly' folded elem its somewhat loosened, thus permittin the access of fluid to the interior of the pac age and the sensitized film. rihis may be assisted by gently pressing the edges of the package, permitting or causing the elements thereof to become slightly separated. The packageiwould appear some- What as shown in Fig. 9. 1t is to be noted that this light trapped but fluid admitting entrance can be made because of the double folding or crimping together of the edges of the foil and the paper and Would be impossible if only a single layer of material Were pressed down around the edge. The

package thus partially opened is droppedthe developing tank is of the common type,

into which the fluids can be poured and from which they canv be drawn by means of suitable tubes, stop-cocks, etc., the process becomes entirely a daylight one. The various pieces of paper referred to are impervious feessie to actinic lightrays but perviou's to X-rays. rlhey may or may, not be Waterproofed. As indicated in certain alternative forms hereinafter described the protecting layers 1'0 may be entirely omitted as may the'sheet 11 and onlylone sheet of sensitized film need be used. ylf this is done it would be preferably sensitized upon both surfaces.y llf the sheets l0 are Water-proofed upon one side only it would be upon that side farthest removed from the films and if the films 2 are sensitized upon one side only it would be upon that side farthest from the foil. The purpose of the additional protective sheets is to avoid any possibility of light entering through pin holes Which might occur in the outer coverings.

if desired, the protective sheets I0 may be of highly absorbent material such as blottingl paper in order to insure that the fluid i admitted to the package along one edge will reach the' entire surface of the film. lf .Inadeof this material the sensitized surface would he placed on that side of the film which would contact these protective papers. lf these absorbent papersare used, it would be possibie to punch notches at selected `points in the edges ofthe package. rlhe package would then in an unopened condition be dropped into a tank of developer and the fluid having access to the absorbent material would permeate throughoutA it'and reach the sensitized surface throughout its entire area. At the most this could not fog more than avery slight extent immediately around the notch and would not affect the recorded image sincethe notches would be made at the points Where fogging would do the least damage.

IFig. l() illustrates a forni in which only one sheet of sensitized film 2 is used and the protective paper is omitted. Sheet 11 is also omitted, the package consisting only of the sheet of foil 3; the film 2 and the outer pa per 4. However, an interlockingbead is formed, the flange 7 being bent at i2y and bent again to form the overhanging fiange 8 around the parts 6 and 5.- On account of the double bending of the fiangef?v it may be opened as shown in Fig. l1 to form the light tight but fluid admitting entrance of the package. F ig. l2 shows another modified form of package similar in' every Way to the preferred form except that the paper 1l is. omitted. As shown in Fig. 13, it may 110e lpartially opened to 'admit fluid but not ig it.

ln the form shown in Fig. 14 the metal foil 8 is made with a flange 5| which is 'longer than theflahge 7 of thepaper 4 and this metallic flangevis bent around the lm and around the paper flange to form the strengthening beadon that side of the film which is opposite to the sheet of foil. rlfhe flange may also be opened as shown in Fig.

surface of the film will be open to exposure' to the X-rays while the advantages gained by use of foil are also attained. These advantages in suchpackages are that secondary radiation is prevented, the 'package is given a greater stiffness and the inter-crlmping of the foil and paper secures without the use of paste or glue, a tight package. When the foil is submitted to pressure 1t fills up cracks and interstices of the bead of whichit is a part. different component parts are shown sepad rated but this is merely for purposes of illus- 'tration' so that the drawings will not be confused except for the space in Fig; 6 between the elements 11 and 3 and the s acing between the elements in the 'parta ly opened packages.

It should be understood that except as limited by the claims, the embodiments here descrihed are to be taken as illustrative only, and that I contemplate as within the scope e use of equiv-aient elements and stepsin manufacture.`

Having thus'described my invention, what I claim as new and desire to 'secure by Letters Patent is:
